CYLINDER-COCK.

CSPECIFICATION forming part of Letters Fatent K0 28450 1, dated September 4, 1883. Application filed April 14, 1853. (No model.)

V To all whom it may concern:

Be it known that I, DANIEL SMULLEN, of the city of St. Louis, in the State'of Missouri, have invented a certain new and useful Im- 5 provement in Cylinder-Cocks; of which the following is a full, clear, and exact descrip tion, reference being had to the accompanying drawings, forming'part of thisrspecification, and in which Figure 1 is a side elevation, showing my improvement attached to a cylinder,'the lower part of the cylinder only being shown. Fig. 2 is a vertical section, in which the operation of the .cock is illustrated by arrows; and 15 Fig. 3 is a side view,'i1lustrating a modified way of arranging the cocks. I

My invention relates to a cylinder-cock for allowing the escape of condensed steam at each stroke of the piston; and my invention described, andpointed out in the claims. Referring to the drawings, A represents part of a cylinder of common construction, and B B escapepipes connecting to the cylinder. one near each end, as shown in Fig. 1. The lower ends of these pipes are preferably connected by a double T-pipe,'O, by means of couplings D, engaging their ends, to up wardlyextending projections O O, and in each of these pipes B B is an automatic cock. These cocks are duplicates, so it will only be necessary for me to describe. one of them, the same letters of reference referring to the other.

E represents a valve having anupwardlyextending stem, F, and a downwardly-extending stem, G. The stem F fits in a central opening of a bridge or cross piece, H, secured to the interior of the pipe B, as shown, or to the coupling-pipeC, and the stem G fits and works in a socket or opening, I, in an extension, 0, of the pipe C. J represents the valve-seat in the pipe 0.

G is the central outlet to the pipe or coupling O. I

When the piston is moving toward the pipe B, the valve in this pipe is opened by a spiral spring, K, allowing the condensed" steam to l 1. escape, as shown by the arrows, Fig. 2, and

roundsthe stem G of the valve, its ends havconsists in points of novelty, hereinafter fully by thev pressure of the live steam, so that the steam cannotescape, and then when the piston moves in the other direction the valve in the pipe B is opened and the other valve closed, and so on. The spiral spring K suring bearing, respectively, against the lower side of the valve and -.the end. of a bolt, L,

screwed into the neck or projection O, and

Bythe adjustment of the collar any desired amount of movement of the valve can behad. The collar also actsto prevent the valve opening against the bridge H, and thus in a measure closing the opening around the valve. Fig. 3 shows a modified formjof the pipes B B, wherein they are straight, and have branch connecting pipes beneath the valves. When the piston is at rest both of thevalves will be opened by the springs.

- I claim as myinvention- In a cylinder-coclnthe combination of main pipe B to connect to. one end of the cylinder,

main pipe B to connect to the other end of the cylinder, coupling 0, having upwardlyextending projections O 0, connected to the adjoining ends of the main pipes, downwardly- 8 5 extending hollow projections O O in line with the upwardly-extending projections, and

central outlet, 0', valves E E, each having an upwardly-extending stem, F, supported by a bridge, H, and downwardly-extending stem G,

9 entering a hollow projection, and surrounded by a spiral valve, elevating-spring, and screwbolts L for adjusting the tension of thesprings,

as set forth.

DANIEL SMULLEN.
